Problem is solved, and no worries that people didn't respond quickly. The little fledges stayed two days in the enclosed patio. I had to be careful opening the door so they wouldn't fly into the house given they panic-fly as they were learning. I did find a stellar jay sitting on the gutter looking into the patio once but it flew off when I entered.

The half of the nest that fell ended up kind of torn apart so I left it. Another part of the nest was partially fell out so the parents had been flying in and out. I was amazed at how well constructed the nest was. Later I'm going to clean the rest out and let them build another one if they choose.
